It is known that ceramic with aluminum hydroxide has certain thermal conductivity, but how to measure the thermal conductivity of ceramics? With this question, let's take a look at the following contents.
Before conducting the measurement, we must first understand what is the thermal conductivity of ceramic parts added with aluminum hydroxide micro powder. Mainly refers to the heat in the unit area of ceramic parts at the specified temperature in unit time. In fact, it is not difficult to understand, but its importance is not low at all, especially for heating furnace materials with good heat storage capacity and good thermal conductivity. If the material has a high thermal conductivity, it can improve the temperature and recovery and utilization of waste heat.
Usually, the thermal conductivity of ceramic parts added with aluminum hydroxide micro powder can be measured in two ways. One is the steady state method and the other is the unsteady state method. When the previous method is implemented, it is necessary to use the plate thermal conductivity meter. The heat flow rate can be measured only by placing the measured parts in a stable temperature field, and the required results are further calculated according to the corresponding calculation formula.
The hot conductance of the ceramic parts is obtained by measuring the temperature of the linear heat source embedded in the ceramic parts by measuring the temperature change of the linear heat source embedded in the ceramic parts.
